VLANS

VLANS

(OP)
So I know what vlans are for and what tagging is. I have a job that has multiple ports being tagged in different VLANS. IE port C24 in 3 different vlans. (vlan 10, 108 and 170) My question is why would you put a port in multiple tagged vlans? My example is there is a server vlan and a voip vlan. There is a port on the switch that is tagged for both vlans. Why I am not sure of because the server does not need to talk to the VOIP vlan. I am concerned because there are some ports with many dropped packets. Thanks in advance.

RE: VLANS

why have a trunk port (multiple vlans):
- connection to a switch or a router on a stick.
- connection to a server running some sort of virtual switch
- connection to a physical server that supports 802.1q

- why tag both voip and XX vlan ? usually that gets plugged into a Phone, the PC is daisy changed to the phone. The phone processes the voip vlan packet, and strips the other xx vlan from the tag and passes it out to the PC..

why are yo concerned?
how did you get this jorb?
